- - - - Character sets
        
        All of the characters that a computer can use are called a character set. This allows the computer system to convert text into binary.
      - ASCII
        
        American Standard Code for Information Interchange (ASCII) A 7-bit character set used for representing English keyboard characters.
      - Extended ASCII
        
        uses eight bits, giving a character set of 256 characters
      - Unicode
        
        While suitable for representing English characters, 256 characters is far too small to hold every character in other languages, such as Chinese or Arabic. Unicode uses 16 bits, giving a range of over 65,000 characters. This makes it more suitable for those situations.
    - - Colour depth
        
        Colour Depth The amount of bits available for colours in an image.
      - Metadata
        
        Data about data, eg photo image files have data about where the photo was taken and which camera took the picture
      - Pixels and resolution
        
        The resolution of an image is a way of describing how tightly packed the pixels are.
